A single-row deep groove ball bearing made substantially of an inner ring and an outer ring disposed coaxially thereto and balls disposed between the rings. The balls roll in deep groove tracks in an outer face of the inner ring and in an inner face of the outer ring, and the balls are held at equal distances to each other in the circumferential direction by a housing. The interior of the bearing is sealed by two circular ring-shaped seals axially opposite each other. At least one of the seals is a lip seal, which has an angular profile. A shape-stable radial seal leg of the seal is attached to the outer ring and forms a gap seal with an axial side of the inner ring, and a sealing lip, which is an overpressure valve, is disposed under the inner ring and slidingly contacts the inner face of the inner ring. |
